7nm CMOS FinFET technology featuring EUV lithography, 4th gen. dual Fin and 2nd gen. multi-eWF gate stack is presented, providing 20% faster speed or consuming 35% less total power over 10nm technology [1]. EUV lithography, fully applied to MOL contacts and minimum-pitched metal/via interconnects, can reduce >25% mask steps with higher fidelity and smaller CD variation. AVT of 6T HD SRAM cell are...
4F2 selector-less crossbar array 2Mb ReRAM test chip with 54nm technology has been successfully integrated for high cell efficiency and high density memory applications by implementing parts of decoders to row/column lines directly under the cell area. Read/write specifications for memory operation in a chip are presented by minimizing sneak current through unselected cells. The characteristics of...
Introduction: Series resistance (Rseries) is a crucial factor for technology optimization and benchmarking [1–3]. Rseries is typically extracted in the bias conditions where Rseries dominates, i.e., linear regime and high Vgs by comparing multiple gate lengths. However this simple extraction is very challenging for sub22nm CMOS devices as changing a device length / width may change mobility or Rseries...
Summary. Clevudine has been approved for the treatment of chronic hepatitis B (CHB) in South Korea. However, its long‐term antiviral effect and safety awaits more study. The aim of this study was to evaluate antiviral efficacy, predictors of virologic response, and development of myopathy after clevudine therapy for CHB. The study included 102 nucleoside naïve CHB patients who had received clevudine...
We report the results of a systematic study to understand low drive current of Ge-based nMOSFET. The poor electron transport property is primarily attributed to the intrinsically low density of state and high conductivity effective masses. Results are supported by interface trap density (Dit) and specific contact resistivity (rhoc), which are comparable (or symmetric) for both n- and p-MOSFETs. Effective...
We have developed a novel dual phase-modulated Ni silicide for Schottky barrier and series resistance reduction in dopant-segregated source/drain (DSS) n-MOSFETs. Using pre-silicide N2+ implant (thereafter N-implant), it is possible to selectively form interfacial epitaxial Si-rich NiSi2, reducing electron Schottky barrier(SB) from 0.7 eV to 0.34 eV while maintaining a low resistive bulk NiSi, at...
